PROBLEM TO BE SOLVED: To provide highly practical and effective new technologies for preventing drowsy driving by elderly drivers, enabling to stably awaken.SOLUTION: A magnetic generator in which magnetic fields are spatially variably distributed is applied to the spinal column of a driver of a moving body. The magnetic generator is the one which generates spatially almost periodic pulse magnetic fields.COPYRIGHT: (C)2013,JPO&INPIT【課題】安定な覚醒が可能であり、実用可能性と実効性の高い、新規な高齢者ドライバーの居眠り運転防止技術を実現する。【解決手段】磁界が空間的に変動分布する磁気発生器を移動体運転者の脊柱部に当てる。【選択図】図2
